PROCESS OF MAKING HEADS FOR MOPS, DUSTERS, OR SIMILAR ARTICLES.

Application filed August 20, 1914. Serial No. 857,706.

To all whom it may concern.-

Be it known that I, CLARENCE W. CARTER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Processes of Making Heads for Mops, Dusters, or Similar Articles, of which the following is a specification. 1

My invention relates to-a process of making heads for mops, dusters or similar articles to be used for cleaning, polishing and the like.

It is the object of my invention to unite in a novel manner a multiplicity of strands of coarse cotton yarn in such manner that the means for holding the strands shall be entirely concealed within the body of the strands.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form,Figure 1 is a plan view of a machine for effecting some of the steps of my process. Fig. 2 is a sectional elevation of the same machine. Fig. 3 is a View of a completed strip of material made by the machine shown in Figs. 1 and 2. Figs. 4 and 5 illustrate how these strips are formed into the material to be employed in the fabrication of the mop heads, sweeping rollers, etc. Fig. 6 illustrates head. Fig. 7 shows the material applied to a sweeping head. Fig. 8 is a view of material 'having uncut loops.

My process consists generally in winding yarn of the desired quality about a pair of strands of flexible wire held in parallel relation, sewing the yarn at the point of looping over said strands of wire so as to bind the same to the wire, thereafter cutting the yarn centrally between the two strands of wire and winding the fabric so formed tightly about a core, preferably of wire or similar material which is capable of being shaped as desired, the fabric being wound with the flexible wire portion next to said coreso that the same will be buried at the center of the substantially cylindrical mass of material having the cut ends of yarn at the outside. Thereafter this cylindrical ,,Specification of Letters Patent.

mass may be formed so as to be applied to a mop head, a brush roller, or any other similar cleaning device.

7 Figs. 1 and 2 illustrate an apparatus for performing the. steps above referred to to the point of completing the brush-making fabric before winding the same upon the wirecore. As there illustrated, a table 10 is provided which has thereon a pair or reels 11 and 12, upon which is wound the wires 13 and 14 about which the yarn is to be woundj Wire 13 passes througha straightening and tensioning device 15 and wire 14 through a straightening and tensioning device 16, from which the wires extend through slots in a circular frame member 17 alongside a guide-plate 18. A drum 19 is mounted to rotate at any desired constant speed on ball bearings about the peripheral surface of frame 17 and carries spider arms 20, each of which is provided with a ball 21 of the yarn to be wound about the wires 13 and 14. Spider 20 with the parts attached thereto extends through an opening 50 in table 10 and is protected o-n the outside by a cylindrical guard 51 secured to the edges of table 10. Tensioning members 22 regulate the feed of yarn from the balls 21 and eflect the delivery of the same about the extreme end of plate 18 at the point where the wires 13 and 14 are leaving said plate. The wires and the yarn wound thereon are uniformly fed forward. by means of driven rollers 23 and 24 engaging the body of the yarn' between the wires, as best shown in Fig. -,1.'

Said rollers may be. moistened with oil or sizing, if desired, by means of spouts 25 and 26 extending from a tank. 27 mounted above the table 10. A supplemental table 33 raised above table 10 so; as to come into the plane of the wires 13 and 14 is provided, upon which are mounted a pair of sewing heads 28'and 29 which operate to sew the loops of yarn 3C immediately adjacentthe wires 13 and 14 so as to-bind said loops of yarn firmly to said wires.

caused to press down upon the edge of the fabric, as indicated in Fig. 2. As the fabric is fed between the edge-gripping devices 31 and 32 it is centrally severed into two parts by means of a circular cutter knife 36 which is driven upon a shaft 37. The material -thus formed comprises strips 38 of yarn looped over and sewed to the wires 13 and 14 and having a multiplicity of free ends 48 extending outwardly from said Wires.

It is to be noted that the wires 13 and 14 are of soft pliable metal which will be entirely flexible and retain the shape in which it may be bent. It is practicable, therefore, to bend this wire about a core of steel wire or other receiving member such as the member 39, indicated in Figs. 4 and 5, the wire 13 being wound tight about the core 39 so as to leave the tuft material 30 extending radially from said central core. By this means the mop-forming product 40 is finally fabricated and comprises a cylindrical body formed of a multiplicity of radially-extended strands of yarn, all of which are firmly bound at the center and which eflectively bury the binding means within said center. As indicated in Fig. (3, the core members 39 may be bent into a semicircular form and the ends brought together radially as indicated at 41 and bound in by a ferrule 42 to which a mop handle 43 is pivotally attached, thus forming a perfect mop head with the means for securing the handle thereto buried at the central part of the brushing or mopping material. Or. as illustrated in Fig. 7, the core 39 may be used as a shaft and have rotating means 44 connected therewith so that an efficient rotary brush is formed.

It is not to be understood that the use of the core or mandrel. about which the fabric composed of the soft wire and yarn tufts is wound, as a former for mop heads or the like is essential to my invention, as the material wound upon the mandrel may readily be stripped therefrom and passed upon a shaped wire comprising the form for the mop head. duster head, brush head or the like. In certain cases it is advantageous to wind the material upon a mandrel slightly larger than the shaped wire for receiving the same and then run the loops formed on the mandrel over the shaped wire to complete the mop head or other article.

The advantages of my invention will be apparent. The brushing material is effectively bound in to the holding means and the ends are everywhere exposed, without any waste or covering. The tufts may be made as long or as short as is desired, and of any desirable material. It is not necessary that the tufts be made of yarn, as fine wire may be employed to form the tufts and can be sewed on to the binder wires 13 and 14 in the same manner. When the material thus fabricated is wound upon the core 39 a circular-wire brushing material is formed, which may be utilized in the same forms of construction as the yarn-made material.

In some cases I omit the step of cutting the strands between the flexible wires upon which the same have been wound; in this case only sewing the loops 30 to one of the wires and thereafter withdrawing the other Wire. In other respects the process is the same. The resulting fabric will have a multiplicity of yarn or wire loops extending radially from the flexible wound wire at the center. This form of material is particularly desirable in making brushing or scrubbing heads or dish mops and the like.

I claim:

1. A method of making brushing material for mop heads or the like which consists in holding a pair of receiving wires in spaced parallel relation, progressively winding about said receiving wires a flexible strand, securing the portions of the flexible strand to the receiving wires inside of the points where the same are looped over the receiving wires, cutting the strands of flexible material midway between the receiving wires, and thereafter winding the receiving wires about a mandrel with the cut strands extending radially therefrom.
